lancelot graphics test: prepare for new host info mechanism

The old hacky way of the test running a "hostinfo.sh" script is about
to be removed, see
https://codereview.qt-project.org/c/qt/qtbase/+/272694

Insted add the value of QT_QUICK_BACKEND (the only
not-automatically-gathered important piece of host information)
programmatically. As a driveby, update it from the obsolete name
"QMLSCENE_DEVICE".
